Dynamic Response of Elastic Beam to a Moving Pulse: A Theoretical Study on Critical Velocity

Abstract:

Dynamic behavior of a semi-infinite elastic beam to a moving single sinusoidal pulse was theoretical investigated. An analytical model was developed based on the Bernoulli-Euler beam theory. The solutions of the deflection and stress of beam were obtained by using the superposition principle and applying the techniques of Fourier transform. It is found that when the moving pulse reaches a critical velocity for a given moving pulse duration, the maximal absolute value of stress in beam attains its maximum value.
